A building automation system may be controlled in response to a natural language voice message. The natural language voice message may be recorded and then sent to a voice command manager via a network. The natural language voice message is then translated into a command recognizable by a building automation controller of the building automation system. Voice recognition software may be used to create a natural language text based message from the recorded natural voice message, and the natural language text based message may then be translated into the command recognizable by the building automation controller. In response to the command, the building automation controller may perform the desired action.
